Dont bother with the oil coolers from euro parts, mk2 gti
1st of all the rubber seal split after about 6 months, So got a new seal from vw dealer cause euro parts didnt stock them, And then after i fitted new seal my expansion tank started 2 fill with creamy water and was runnin all through my pipes, what a mess that was,
So i thought my head gasket had gone, But a local mechanic said it could be my oil cooler, So i robbed a genuine oil cooler of a mk3 gti in scrappy, And it has been fine, that was 2 years ago,,
